"given a nodal delay of 84.1ms when there is no traffic on the network (i. e. usage = 0%), what is the effective delay when network usage = 39.3% ? (give answer is miliseconds, rounded to one decimal place, without units. so for an answer of 0.10423 seconds you would enter "104.2" without the qu"

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
